GeForce GTX 780 Gainward Phantom Edition is a special edition of the high-end GeForce GTX 780. This edition comes with a custom triple fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology. Also, it has been overclocked out of the box from 863MHz to 902MHz while its boost clock is now of 954MHz. The memory clock was left untouched. Benchmarks indicate a 5% performance boost when compared to the reference card.
